Just a quick question

I have an issue with my autoflower white widow. Seems that the upper leaves are showing signs of issues. Almost like a purple black mass going from outer leaf to inner. My ph is around 6.3, I'm growing organically in soil. Yes my leaf tips are a little yellow, that was my oregonism xl overstimulating nutrients in veg. I have well rounded nutes, using bloom and a foundation. Also I'm using liquid kelp for potash, domolite lime for calmag. I have been supplementing cal mag because I use ro water. Lights are not burning plants plants od distance, the temps are around 75 lights on and 65 lights off. Humidity is around 35 to 40 during flower. Can someone ponder some ideas of what's going on?

You don't say exactly how much you're feeding or how often. Soil traps nutrients, which means you don't have to fert all the time. Yellowing leaf tips and leaf death usually mean over fertilization. It looks like you're giving a lot of stuff, perhaps too frequently. Just give water for a while after the soil dries out and see what happens. Don't water to flush, just get a small amount of runoff out the bottom. Use a wet/dry cycle. let soil dry out quite a bit, then water again.

I guess I did miss that fine detail. I have only fed the plants one single time. I am using roots organics dry nutrients. I started with a half strength dose. The widow is over 5 weeks old. I fed its first dose at 4 weeks. From there on I have not fed it.

The widow is under a cmh, a round 18 inches above. There is a fan blowing over the canopy of the plants.

Roots organics original. Amended with extra perlite.

So funny thing guys it ended up being a potassium and phosphorus deficiency. Getting much better now that I added. The over fertilization like I said came from the roots organics oregonism xl. They say feed as much as you want, In which I didnt do. The small amount I did feed made the plant go into overdrive and absorb nutrients to fast in the first floweing stage.

You wrote earlier that you hadn't fed it much so, yeah, that's what I was thinking.

Krzyżaka widze!
